Astronomers Find Star-Within-a-Star, 40 Years After First Theorized 59

Originally predicted in the 1970s, the first non-theoretical TZO was found earlier this year, based on calculations presented in a paper forthcoming in MNRAS.

TZOs were predicted by astronomer Kip Thorne and Anna Zytkow, who wasthen postdoctoral fellow at CalTech. The pair imagined what might happen if a neutron star in a binary system merged with its partner red supergiant. This wouldn't be like two average stars merging. Neutron stars are the ancient remnants of stars that grew too big and exploded. Their cores remain small — about 12.5 miles across — as they shed material out into space. Red supergiants are the largest stars in the galaxy, with radii up to 800 times that of our sun, but they aren't dense.

The laws of war generally oppose weapons intentionally intended to maim rather than kill. Mostly dates to popular revulsion around the WW1 era over weapons designed to inflict nonlethal but gruesome casualties to hobble the other side by flooding their hospitals and supply chains. As a result, countries agreed to a ban on various chemical weapons, expanding bullets, weapons designed to blind people, etc.

Crazy, isn't it?

Evidently, there is some unwritten law that states that Geolocation by IP address shall override any and all set preferences by the user on their device, and ignore any possibility that barring or redirecting the user makes no sense.

I get a version of this periodically on Spotify, where I'm informed that the particular album or single I'm looking at can't be played because it isn't licensed to my region. And of course there's the small matter of my being IP-blocked from Pandora Radio for the same reason.

I ran into a particularly nasty geolocation issue back in late 2012, when I was informed that I couldn't access my National Lottery account because they no longer believed that I was accessing it from the UK. Went back and forth between them and my ISP (VirginMedia), with each blaming the other for the problem.

I've also heard of situations where people have found the books on their Kindles vanishing because they're holidaying in an area where said books aren't licensed.

Many religious people depart from science the moment it begins to conflict with their own insane views of how the world (and the universe) works. Some religious people feel that there is no contradiction between science and religion, and rationalize it as science discovering God's rules. Honestly I don't have a problem with this, since we don't really know who (if anyone) made the rules.

Atheists tend to like science because it's grounded in fact, and isn't bound to blind faith which I find is also reasonable. Religion has never really proven itself to be anything other than a source of control over people's lives and its value is at best, questionable.

Our problem isn't with cyclists on the road, it's with how cyclists conduct themselves on the road. The real problem is that cyclists seem to think traffic laws don't apply to them and in doing so put everyone else - including themselves - at risk. You should be fined, have your bike confiscated, and be barred from riding if you're *ever* caught disobeying road rules. Especially a failure to signal, which is something cyclists constantly do. It's too bad you're too dense to understand this.

Bringing computers into the home won't change either one, but may revitalize the corner saloon.
